Beschreibung

Application

Potassium sodium tartrate tetrahydrate can be used as a:

• Reducing agent in the preparation of monodispersed gold nanoparticles.
• Key component in the preparation of Fehling′s solution, which is used to distinguish between reducing and non-reducing sugars.
• Chelating agent to prepare Co-Ni-P/Pd-Al₂O₃ catalyst through electroless deposition method.
